Seat finding supports minPitch and minWidth in inches and repeated equipment filters (power, ac_power, usb_power, wifi, screen). All preferences apply together; ranges use their lower bound and unknown dimensions do not match a minimum. Link travelers to the returned guideUrl.

## Reading a guide
Aircraft pages include cabin tables and a seat-by-seat table in the initial HTML, with collection dates and layout warnings. Facts use inches where marked. Missing seat notes do not mean a seat has no drawbacks. Seat maps are schematic, not scale drawings. Confirm the exact aircraft configuration with the airline. No live seat availability or booking service is provided. Reviews are traveler-reported.
